It has been suggested that a suppression of maximal voluntary contraction (MVC) induced by prolonged vibration is due to an attenuation of Ia afferent activity. The purpose of the present study was to test the hypothesis that aftereffects following prolonged vibration on muscle activity during MVC differ among plantar flexor synergists owing to a supposed difference in muscle fiber composition. The plantar flexion MVC torque and surface electromyogram (EMG) of the medial head of gastrocnemius… Expand
Acute effects of Achilles tendon vibration on soleus and tibialis anterior spinal and cortical excitability.
TLDR
The high modulation of Ia afferent input by vibration led to changes in motor cortex excitability that could contribute to the enhancement in muscular activation capacities reported after chronic use of tendon vibration. Expand
No Alteration of the Neuromuscular Performance of Plantar-Flexor Muscles After Achilles Tendon Vibration
TLDR
It is demonstrated that 30 min of Achilles tendon vibration at a low or high frequency using a portable stimulator did not affect the neuromuscular performance of the PF muscles, emphasizing the limits of tendon vibration, whatever the frequency applied, for inducing neuromUScular fatigue. Expand
Effects of prolonged vibration on H-reflexes, muscle activation, and dynamic strength.
TLDR
The findings suggest that Ia-afferent input may not substantially contribute to maximal voluntary dynamic muscle strength of the plantar flexor muscles, as tested here, and thus, the results do not support the notion that Ianafferent excitation would contribute differently to neural activation in maximal voluntary lengthening and shortening muscle actions. Expand
Changes in tibialis anterior corticospinal properties after acute prolonged muscle vibration
TLDR
Dorsiflexion maximal force production capacities were unaffected by 30 min of tibialis anterior muscle vibration, despite spinal loop and corticospinal excitabilities being reduced, suggesting that acute prolonged vibration has the potential to modulate corticOSPinal excitability of lower limb muscles without a concomitant functional consequence. Expand
Acute effects of passive stretching and vibration on the electromechanical delay and musculotendinous stiffness of the plantar flexors.
TLDR
The present findings indicated that the stretching- and vibration-induced force deficits may have resulted in part from similar centrally-mediated neural deficits, while an elongation of the series elastic component may also have affected the stretching -induced force deficit. Expand
Acute effects of passive stretching vs vibration on the neuromuscular function of the plantar flexors
TLDR
Both PS and VIB elicited similar neural deficits (i.e., γ loop impairment) that may have been responsible for the strength losses, but mechanical factors related to PROM and MTS cannot be ruled out as contributors to the stretching‐induced force deficit. Expand
Acute effect of tendon vibration applied during isometric contraction at two knee angles on maximal knee extension force production
TLDR
Results clearly demonstrate that acute infrapatellar tendon vibration using a commercial apparatus operating at optimal conditions (i.e. contracted and stretched muscle) does not appear to induce knee extensor neuromuscular fatigue in young sedentary subjects. Expand
Acute postural modulation of the soleus H-reflex after Achilles tendon vibration
TLDR
The results of the present study suggest that presynaptic inhibition could have largely contributed to the H-reflex decrease observed after one bout of vibration. Expand

TLDR
Lower brain activity following short-term local Achilles tendon vibration may indicate improved cortical function during a submaximal dynamic exercise in female young soccer players. Expand

TLDR
Repeated vibrations of the Achilles tendon lead to an increase in plantar-flexor activation and thus to greater force developed in voluntary conditions whilst the contractile properties assessed by the twitch are not modified. Expand

Prolonged muscle vibration reducing motor output in maximal voluntary contractions in man.
TLDR
It is argued that the vibration‐induced suppression of motor output in MVCs probably does not depend on alpha‐motoneurone inhibition, but on a reduced accessibility of these neurones to the voluntary commands, and contributing mechanisms might be vibration‐ induced presynaptic inhibition and/or ‘transmitter depletion’ in the group Ia excitatory pathways which constitute the afferent link of the gamma‐loop. Expand
Central and peripheral contributions to fatigue in relation to level of activation during repeated maximal voluntary isometric plantar flexions.
TLDR
The results indicate that both central and peripheral mechanisms contributed to the fatigue observed during repeated MVCs and that the development of peripheral fatigue was influenced by the level of voluntary activation and initial plantar flexor torque. Expand
Tonic vibration reflexes elicited during fatigue from maximal voluntary contractions in man.
TLDR
Results on human foot dorsiflexor muscles agree with the hypotheses that in sustained MVCs, fatigue processes occur not only in extrafusal but also in intrafusal muscle fibres and that vibration‐induced activity in group Ia afferents can act as a substitute for the diminished fusimotor drive. Expand
Decrease in maximal voluntary contraction by tonic vibration applied to a single synergist muscle in humans.
TLDR
The present results indicate that MVC and dF/dt(max) may be influenced by the attenuated Ia afferent functions of a single synergist muscle. Expand
Altered reflex sensitivity after repeated and prolonged passive muscle stretching.
TLDR
Evidence is presented that the mechanism that decreases the sensitivity of short-latency reflexes can be activated because of RPS, and the origin of this system seems to be a reduction in the activity of the large-diameter afferents, resulting from the reduced sensitivity of the muscle spindles to repeated stretch. Expand
Prolonged muscle vibration reduces maximal voluntary knee extension performance in both the ipsilateral and the contralateral limb in man
TLDR
It was concluded that muscle vibration may act through spinal reflex pathways to influence the homonymous mot oneuron pool and suggest an effect on heteronymous motoneuron pools or an effect acting on central descending drive to contralateral muscles. Expand
Tendon vibration-induced inhibition of human and cat triceps surae group I reflexes: Evidence of selective Ib afferent fiber activation
TLDR
The findings supported the proposal that postvibration depression of soleus H-reflexes in humans or cats is caused by both disfacilitation and autogenetic inhibition due to withdrawal of Ia afferent activation and increased selectivity of Ib afferent fiber stimulation, respectively. Expand
Failure of neuromuscular propagation during human maximal voluntary contraction.
TLDR
The results suggest that the loss of force of the adductor pollicis with fatigue and its subsequent recovery are largely determined by the extent of neuromuscular propagation failure, and the slow recovery of the M-wave amplitude during repetitive stimulation suggests that it may be related to some aspect of muscle metabolism. Expand
Significance of peripheral afferent input to the α-motoneurone pool for enhancement of tremor during an isometric fatiguing contraction
TLDR
It is concluded that the enhancement of isometric tremor seen during a fatiguing submaximal isometric contraction is facilitated by peripheral afferent input to the α-motoneurone pool. Expand
Muscle membrane excitation and impulse propagation velocity are reduced during muscle fatigue
TLDR
A reduction in both the level of excitation and impulse propagation velocity of muscle membranes occurs during muscle fatigue, and the magnitude of this reduced membrane function and its contribution to the mechanisms underlying fatigue depend both on the duration and degree of fatigue, as well as on the intrinsic properties of the particular muscle.
